WIRE BRUSH.

, .ttlSdtDEt T 0 (iZZ whom it may 0017 oer-n Be it known that I, Rnnonv iii-131v, a citizen of the Aachen, new and usefulImprovements in and ing to Wire Brushes, of which the is a specification.

My present invention has for its object to provide an improved wire-brush made entirely from metal. The characteristicfearesidesin the fact that an oval slightly arched metal plate has a downturned edge to embrace a wire carrying sheet made of compound rubber-cloth and supplied or fitted mechanically in oval form with fine wires. The two-armed1ll shaped wires bear with their base portion against a layer of felt, secured to the back of the sheet of rubber-cloth and preventing said wires from passing therethrough, said layer of felt together with the metal plate forming a narrow air cushion which provide for the cushioning of the bottom of the brush. Said air cushion will be re-formed after each depression of the brush, owing to the fact that the double U-shaped wires, the arms of which slightly diverge towards the points thereof, cause the upper side of the rubber sheet to be tensioned and arched.

My present wire-brush which may first be used as a brush, a curry-comb, or a hairbrush as well as for other purposes is illustrated in one form of embodiment (currycomb) in the accompanying drawing, wherein:

Fig. 1 is a vertical section and Fig. 2 a perspective view of the improved brush.

The oval metal plate a is preferably formed of a light and durable aluminium alloy and slightly arched towards the center thereof, the convex face of the plate being turned towards the wires 5. The peripheral edge of said plate is curved on an arc of cirole 0 and said curved edge embraces the peripheral edge of the wire carrying sheet (Z to secure the same in place. Said wire carrying sheet is formed of thin rubber-cloth and fitted mechanically in oval form with fine compact wires. The double wires bent in a well-known way in the shape of U, bear with their base portion against a layer of felt e applied to the back of the rubbercloth and preventing the wires from passing Relatfollowing therethrough. Provided between said layer Specification of Letters Patent.

w p 7 Application filed April 19, 1921.

German Republic, and resident of Germany, have invented certain Patented Mar. '7, 1922. Serial No. 462,537.

offelt and the metal plate a is an air space 7 which gives the bottom of the brush a yielding elastic nature. Said air space is not provided asfor instance in a pneumatic motion by inflation by means of a pumpwhich has'alre'ady been proposed previously for hair brushes-but said air cushion will be immediately l e-formed after each depression of the brush in use, owing to the fact that the U-shaped wires, the arms of which 65. slightly diverge towards the points thereof, act to subject the upper side of the rubber cloth to tension and arch the same. At the same time the layer of rubber prevents dirt from impregnating the layers of cloth of the v bottom of the brush. In order to facilitate the manipulation of the brush serving as a currycomb,' the upper face of the metal plate is provided with a strap 9. In hairbrushes a suitable handle is substituted for said strap. p

In hair-brushes the strands or wires are arranged at right angles to the bottom of the brush, whilst in combined brushes and curry combs said wires are preferably inclined at an angle to the elastic bottom, whereby the same brush may be used for carrying coarse and fine haired horses, the brush being either passed against the hair (coarser and harder) or in the direction of the hair (finer and softer). The brush may also be used primarily for currying purposes, that is for the 'removal of heavy dirt and the combing of I hair sticking together. To this end the outer face of the metal plate a may be provided with suitable words such as hard and soft as with arrows to indicate the kind and direction of cleaning in every case.

A hair brush or curry-comb of the kind described is distinguished by its fiery little weight and an extraordinary superior grooming action. Said brush completely avoids the use of a curry-comb proper. In contradistinotion to the latter, it does not pull out implanted hair from horses and it will perfectly remove dirt and pellicles from the skin and hair. After a short time the latter will be quite brilliant and have a velvet-like softness.

The strainthat is necessary for grooming horses is much lighter than with the use of ordinary curry-combs, because the yieldingly supported wires of the brush; are adapted to pass more easily than rigid bristles onto the skin or scalp. The time planted hair.

. ofthe bottom of the brush owing to that is necessary for thoroughly grooming a horse is according to practical experiments-about a quarter of the time that is necessary. with the use of an ordinary currycomb or brush.

Hair-brushes may the same principle with some suitable modifications and may be advantageously used according to experiments, made heretofore.

With a brush of this kind the thickest and most entangled womans hair may be disentangled and combed without any appreciable strain, so thatthe usual hair-comb may be dispensed with except for 15 the dressing proper of the hair. As hair-brushes n contradistinction to brushes or curry combs are subjected to strains in the direction of their transverse 'aXlS lQlIG wiresof said brushes will not be inclined but arranged atright angles to the bottom of the brushes as already stated. In contradistinction to the usual comb, my improved wire brush avoids nearly completely the pulling out of Well im- This advantage which is in valuable for the preservation of well cared wo-mans hair proceeds on one hand from the great elasticity of the fine wire and on the'other hand from the perfect cushioning the use of rubber material in conjunction with the intermediate air space. Atthe places where thehair is toostrongly entangled, the smooth yielding wi'resimply glides overv the same, whilst the rigid comb pulls the hair out with be made according to Having now fully described my said in vention, what I claim and desire to secure joy Letters Patent, is:

3. brush having an elongated back member formed of sheet material thereof and having the edge portion turned arched transversely downwardly and inwardly to form a bead, a wire carrying sheet having wire bristles secured therein perpendicular to its surface. said sheet having its edge portion extended into the head of the back portion and retained therein, a felt pad between the back member and the sheet to provide an abutment for the wires in the sheet, and a handle secured to the back member whereby the arched back member will retain the wire carrying sheet in arched shape to cause the wire bristles to diverge toward the outer ends.

In testimony whereof I have hereunto set my hand in presence of two witnesses.
